I got a problem on my web development using CanvasJS. Indeed, I catch my datas and I normalize these datas to a JSON compatible with CanvasJS. When I use, the example, all is ok, It displays the chart correctly. But when I use my JSON, that doesn’t work anymore. Look at these screenshot, you will understand. It displays the popup with the perfect datas, but doesn’t display the lines and the points which represents the curve.

This is the pictures that show my problem. As you can see the JSON object is ok, but I can’t see the squares and the lines of my chart ! The squares at the bottom of the chart represent the value 0. The others don’t exist. Thank you for your help !

We tried but are unable to reproduce the issue at our end. Can you please let us know the version of CanvasJS that you’re using? Also, can you please mention your browser version along with OS?
You can also try disabling hardware acceleration in your browser and check if it makes any difference.
